To @ZZ whom it 11i/ay concern,.-

Beit known that I, JACOB BBEAM, a citizen ofthe United States, residingat Bigrumin the county ot' Jefferson and State of Pennsylvania, haveinvented certain new and useful Improvements in Oil-Cans, of which thefollowing is a specification.'

My invention relates to that class of oilcans in which pumping apparatusis employed for forcing oil from the spout; and the object of myinvention is to equip an oil-can with improved pumping apparatus whichmay be easily applied to or removed from the can, may be easilyoperated, and which while simple in construction is efficient inoperation.

In carrying out my invention I provide an oil-can of ordinaryconstruction with a removable bottom, to which is attached a cylinderconnected with'the interior of the can by a valved passage and in whichoperates a valved piston, whichis reciprocated by a tube whichtelescopes with the spout of the can and moves up and down therein. Thetube is reciprocated by means of a bell-crank lever pivoted on a bracketwithin the can and con-l nected by means of jointed rods or links with ahand-lever located within the handle of the can and pressed in onedirection by a spring, the arrangement being such that the can may beheld by one hand in the usual way and operated by the same hand to expelthe oil,

-while the other hand of the user may be unemployed or employed in someother way.

In the accompanying drawings, Figure lis a view, partly in sideelevation and partly in section, ot' an oil-can embodying myimprovements. Fig. y2 is a View, onran enlarged scale, of the lower partof the can with parts broken away to illustrate Vthe mechanism containedwithin the can. Figs. 3 and are detail views of the cage employed forconfining the ballvalves.

The main body of the can Ais of the usual construction and basa spout Bof the ordinary kind. The bottom of the can is formed with a centralopening around which is a depending screw-threaded'tlange a, adapted toengage a screw-threaded flange c on a cap C, that closes the bottomopening. A rubber gasket a' is preferably interposed between the upperend of the ange @and the bottom ofthe can in order to form a tightjoint.

Serial No, 151,829. (No model.)

the cap C is attached the cylinder D of the pumping apparatus. Theinterior of the cylinder communicates with the interior ot the `can bymeans of a valved passage E. The pipe e of this passage extends from anopening e' in the side of the cylinder near its lower end to the centralportion ot the cylinder, where it is provided with a cage F, containinga ball-valve f. The cage F is preferably formed in the manner indicatedin Figs. 3 and 4, being stamped from sheet metal with the circularcentral portion f' and four radial arms f2. The arms are bent, and thecentral portion is made concave-convex, in the manner indicated in Fig.It, the outer ends of the arms being attached to the inner end of thetube e in the manner indicated in Fig. 2, thus leaving openings ai, bywhich communication may be established between the intee rior ofthecylinder and the passage E. The inner end of the tube e-is properlyformed with a valve-seat to accommodate the ballvalve. The piston Gis'tted to reciprocate easily but tightly in the cylinder D. It isattached to a tube H, which latter telescopes at h with another tube ortubular guide I, arranged within the spout B, extending nearly to theupper end thereof and being braced and secured at its lower end by rodsJ, attached to the can. The -tube I-I is adapted to reciprocatelongitudinally in the tube I. The piston is provided with avalve-chamber K, containing a cage L, similar to the cage F, withinwhich is a ballvalve M, itting a valve-seat arranged over an opening min the piston. lNhen the ball-valve falls or is in its lowermostposition, the opening between the cylinder and the tube H is closed; butwhen the ball-valve rises, as it does when the piston descends,communicationis established between the interior'of the cylinder and thetube II. i

By the arrangement described when the piston rises the valve f opens andoil may be drawn from the interior of the can into the linterior of thecylinder D, the valve M at this time being closed. When the pistondescends, the valve f closes, while the valve M opens, and oil may passthrough the opening m into the tube Il, and from the tube H oil passesinto the tube I and then out through the spout.

lCO

cate the piston, I em ploy mechanism arranged within the handle N of theoil-can and connected with the piston in such manner as to operate iteasily by an easy movement of the ngers. The tube H is provided withlaterally-projecting studs or arms n, which are embraced by thebifurcated ends o of a bellcrank lever O, pivoted to a bracket P withinthe can and having its shorter arm o' slotted at 02 and connected with arod Q, that reciprocates through a stuffing-box R, and is connected bymeans of a link S to a lever T, the main port-ion of which is disposedvertically, but which has a lower curved-end t, pivoted to a bracket t',attached to'the outside of the can. The handle N is preferably curved inthe manner indicated, and to it is attached a leaf-spring U, which atits outer free end bears against the lever T and tends to move thebell-crank lever in such direction as to lift the piston.

In operation the hand which grasps the handle may easily draw the leverT outward in such manner as to depress the piston, and thus force oilout through the nozzle. When the fingers are released from the lever T,the spring U acts to lift the piston, and thus draw more oil into thecylinder D. By repeatedly operating the lever T in this way the cylinderD may be filled, and oil may be forced out through the nozzle.

Among the advantages of the construction described are that the pumpingapparatus may be easily attached to and taken from the oil-can. Byremoving the cap C the cylinder and parts attached thereto may be easilytaken out, and I may employ a removable plate V, carrying the bracket P,stuffing-box R, and the bracket t'. By removing the plate the lever O,lever T, and parts connected therewith may be detached.

I claim as my invention- 1. rThe combination of an oil-can having anopening in the bottom and a spout at the top, a guide-tube within thespout, a tubular piston-rod telescoping with the guide and detachabletherefrom, a cap detachably secured to the can and covering the openingin the bottom thereof, a pump-cylinder secured to 'the cap and removabletherewith from the the cylinder.

2. The combination ofl an oil-can having an opening in the bottom andformed with a depending screw-iiange around the opening, a cap having avertical screw-flange engaging the flange on the bottom of the can andcovering the opening therein, a pump-cylinder attached tothe capremovable therewith from the can and having an annular surrounding spacewithin the cap, a valved passage connecting such annular space in theAcap with the interior ofthe cylinder, a piston reciprocating in thecylinder, a valved passage leading from the cylinder through the piston,and means for reciprocating the piston.

3. AThe combination of an oil-can having a discharge-nozzle, a pumpwithin the can, valved passages connecting the pump with the interior ofthe can and with the nozzle, a bell-crank lever arranged inside the canand having av bifurcated end loosely and detachably connected with thepiston of the pump, a handle for the oil-can, an oscillating leverarranged Within the handle, and connections between the oscillatinglever and the bellcrank lever.

4. The combination of an oil-can having a discharge nozzle, a pumpWithin the can, valved passages connecting the pump with the interior ofthe can and with the nozzle, a bell-crank lever arranged inside the can,a plate removably connected with the can to which said bell-crank leveris pivoted, detachable connections between the bell-crank lever and thepiston-rod of the pump, a handle for the oil-can, an oscillating leverarranged within the handle and pivoted to said removable plate, andconnections between said oscillating lever and said bell-crank lever.

In testimony whereof I have hereunto subscribed my name.
